Oncologic outcomes of intersphincteric resection versus abdominoperineal resection for lower rectal cancer: a systematic review and meta-analysis. Int J Surg 2024; 110:2338-2348. [PMID: 36928167 PMCID: PMC11020000 DOI: 10.1097/js9.0000000000000205] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2022] [Accepted: 11/20/2022] [Indexed: 03/18/2023]
Abstract
BACKGROUND The efficacy of intersphincteric resection (ISR) surgery for patients with lower rectal cancer remains unclear compared to abdominoperineal resection (APR). The aim of this study is to compare the oncologic outcomes for lower rectal cancer patients after ISR and APR through a systematic review and meta-analysis. MATERIALS AND METHODS A systematic electronic search of the Cochrane Library, PubMed, EMBASE, and MEDLINE was performed through January 12, 2022. The primary outcomes included 5-year disease-free survival (5y-DFS) and 5-year overall survival. Secondary outcomes included circumferential resection margin involvement, local recurrence, perioperative outcomes, and other long-term outcomes. The pooled odds ratios, mean difference, or hazard ratios (HRs) of each outcome measurement and their 95% CIs were calculated. RESULTS A total of 20 nonrandomized controlled studies were included in the qualitative analysis, with 1217 patients who underwent ISR and 1135 patients who underwent APR. There was no significant difference in 5y-DFS (HR: 0.84, 95% CI: 0.55-1.29; P =0.43) and 5-year overall survival (HR: 0.93, 95% CI: 0.60-1.46; P =0.76) between the two groups. Using the results of five studies that reported matched T stage and tumor distance, we performed another pooled analysis. Compared to APR, the ISR group had equal 5y-DFS (HR: 0.76, 95% CI: 0.45-1.30; P =0.31) and 5y-LRFS (local recurrence-free survival) (HR: 0.72, 95% CI: 0.29-1.78; P =0.48). Meanwhile, ISR had equivalent local control as well as perioperative outcomes while significantly reducing the operative time (mean difference: -24.89, 95% CI: -45.21 to -4.57; P =0.02) compared to APR. CONCLUSIONS Our results show that the long-term survival and safety of patients is not affected by ISR surgery, although this result needs to be carefully considered and requires further study due to the risk of bias and limited data.

Analysis of presacral tissue structure in LARS and the prevention of LARS by reconstruction of presacral mesorectum with pedicled greater omentum flap graft. Tech Coloproctol 2021; 25:1291-1300. [PMID: 34581900 DOI: 10.1007/s10151-021-02521-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/26/2021] [Accepted: 09/04/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND The greater omentum has played a unique biological role in regenerative surgery. The aim of our study was to alter the anterior sacral structure by filling the anterior sacral space with the greater omentum and evaluate its effect on the low anterior resection syndrome (LARS) after total mesorectal excision (TME) surgery for low rectal cancer. METHODS We retrospectively collected clinical data of patients with primary low rectal cancer who underwent TME and ileostomy closure in our hospital from March 2018 to March 2020. Spearman correlation analysis was conducted to analyze the correlation between postoperative mesorectal fascia (MRF) thickness and LARS score. Subsequently, we prospectively used a tipped greater omental flap graft to reconstruct the anterior rectal sacral structures (MRF reconstruction) in 17 patients and compared LARS scores and rectal compliance (RC) at week 12 after closure of the ileostomy in both groups. RESULTS There were 47 patients with No-MRF reconstruction (31 males, mean age 60.68 ± 9.21 years) and 17 with MRF reconstruction (10 males, mean age 49.82 ± 14.74 years). Correlation analysis indicated that MRF thickness and RC were negatively correlated with LARS severity (p < 0.05). The LARS score of patients with MRF reconstruction at 12 weeks was significantly better than that of those with No-MRF reconstruction (32.97 ± 2.65 vs. 26.94 ± 1.52, p = 0.001), and the RC of MRF reconstruction were lower (2.80 ± 0.55 vs. 3.67 ± 0.38, p = 0.001). In addition, MRF reconstruction and No-MRF reconstruction have the similar incidence of postoperative complications (p = 0.156). No hemorrhage or necrosis of the greater omentum flap was observed in any of the patients. CONCLUSIONS Greater omentum flap transplantation can significantly improve the symptoms of LARS at 12 weeks after ileostomy closure and we expect it to become a new surgical procedure for the treatment of low rectal cancer.

Abstract
BACKGROUND The surgical treatment options for low rectal cancer patients include the Abdominoperineal Resection and the sphincter saving Low Anterior Resection. There is growing evidence towards better outcomes for patients being treated with a Low Anterior Resection compared to an Abdominoperineal Resection. OBJECTIVE The aim of this study was to evaluate the short term and oncological outcomes in low rectal cancer treatment. DESIGN This is a retrospective cohort study of prospectively collected data. SETTING Rectal cancer patients from a single center in the United Kingdom. PATIENTS Patients included all low rectal cancer patients (≤ 6 cm from the anal verge) undergoing Low Anterior Resection or Abdominoperineal Resection between 2006 and 2016. OUTCOME MEASURES To identify differences in postoperative complications and disease free and overall survival. RESULTS A total of 262 patients were included for analysis (Low Anterior Resection n = 170, Abdominoperineal Resection n = 92). Abdominoperineal Resection patients were significantly older (69 versus 66 years), had lower tumours (3 versus 5 cm), received more neo-adjuvant radiation, had longer hospital stay and more complications (wound infections and wound dehiscence). Low Anterior Resections had a significantly higher number of harvested lymph nodes (17 versus 12) however there was no difference in nodal involvement and R0 resection rate. No significant difference was found for recurrence, overall survival and disease free survival. LIMITATION Retrospective review of cancer database and single center data. CONCLUSION In the treatment of low rectal cancer Abdominoperineal Resection is associated with higher rates of postoperative complications and longer hospital stay compared to the Low Anterior Resection, with similar oncological outcomes.

Abstract
BACKGROUND In patients with ultralow rectal cancer, surgical resection of the tumor without impairing sphincter function remains a technical challenge. The purpose of this study was to describe a new technique of transanal natural orifice specimen extraction (NOSE) surgery using our independently developed devices, aiming to achieve precise cancer resection and preserve sphincter function in patients with ultralow rectal cancer. METHODS Precision functional sphincter-preserving surgery (PPS) was performed on nineteen patients with ultralow rectal cancer between June 2019 and April 2020. With the help of our independently developed devices, surgeons directly and accurately removed the lower edge of the tumor and retained healthy rectal tissue on the nontumorous side. Hand-sewn anastomosis with a mattress suture was used to achieve sturdy anastomosis. Preoperative baseline characteristics, operative details, 90-day postoperative complications, costs, and anal function score at 6 months after surgery were documented. RESULTS Nineteen ultralow rectal cancer patients with a median distance to the dentate line of 2.0 cm successfully underwent PPS without serious postoperative complications. Six out of nineteen patients (31.6%) received a prophylactic stoma. The average cost was 62164.1 yuan. At 6 months after surgery, the average Wexner anal function score and the average Vaizey score were both 3 points. CONCLUSIONS PPS can be employed to precisely resect rectal tumors and preserve sphincter function in ultralow rectal cancer patients. The use of our devices enhanced surgical efficiency, reduced the need for prophylactic stoma, reduced surgery-related costs, and prevented abdominal surgical incisions.

Abstract
PURPOSE To investigate the frequency of exfoliated cancer cells and the efficacy of rectal washout during intersphincteric resection (ISR) in patients not receiving chemoradiotherapy (CRT) for very low rectal cancer. METHOD The subjects of this prospective study were 16 consecutive patients who underwent ISR without CRT for very low rectal cancer. Brushing cytology of the posterior anorectal wall was performed twice in each step of the ISR procedure and the samples were sent for blind cytological examination to identify exfoliated cancer cells. RESULTS Exfoliated cancer cells were identified in 9 of 13 patients (69%) preoperatively. The number of cancer cells identified after abdominal total mesorectal dissection decreased significantly from 94% (15/16) to 25% (4/16) after transanal irrigation with 2000 mL saline (p < 0.001). No cancer cells were identified after swabbing the anal wall following transanal dissection with purse-string closure of the distal stump. No suture-line recurrence was found during a median follow-up duration of 6 years. CONCLUSION Exfoliated cancer cells, confirmed in 94% of patients after total mesorectal excision, could be eliminated by performing rectal irrigation after clamping the rectum proximal to the tumor and swabbing the anorectal wall during ISR.

Abstract
Background: This study represents a prospective analysis of a series of laparoscopic ultra low anterior resection (ULAR) done at a laparoscopic surgical center to assess the surgical outcome, oncological efficacy, and quality of life after surgery. Methods: Over a period of 6 years (2013-2018), 43 patients aged between 40 and 68 years, with very low rectal cancers (3-6 cm from the anal verge), within T3N1M0 stage, assessed by positron emission tomography-computed tomography and pelvic magnetic resonance imaging, underwent neoadjuvant chemoradiotherapy (nCRT) followed by laparoscopic ULAR and simultaneous diversion ileostomy. Results: The overall complication rate was low and there was an overall leak rate of 9.3% with a radiological leak (Grade A) in 3 of the 43 patients (7%), but only 1 (2.3%) patient required a local lavage and a resuturing for secondary hemorrhage. Recurrence was seen in 2/43 (4.7%), one of whom had a conversion to abdominoperineal resection. The other had distant metastasis and refused further treatment. The functional outcome is assessed in 41 (95.3%) patients by low anterior resection syndrome (LARS) score and a reasonable quality of life with major LARS was seen in only 7.3% of the patients at a follow-up ranging from 1 to 6 years. Conclusion: The nCRT followed by laparoscopic ULAR is a feasible option for operable very low rectal cancers and is associated with minimal postoperative events, a low local recurrence and less incidence of LARS.

Abstract
AIMS AND OBJECTIVES The purpose of this study was to explore the prevalence of sexual dysfunction in males one year after undergoing low anterior resection and to determine whether health care professionals discuss sexual issues with patients after surgery. BACKGROUND Sexual dysfunction in males may be a complication after low anterior resection for rectal cancer, but few studies have explored this issue in Taiwan. DESIGN A descriptive comparison study design. METHODS A descriptive comparison design was used, and a group of 133 participants underwent a low anterior resection procedure for rectal cancer. The results were compared with those of a group of males who underwent colectomy (n = 58) for colon cancer. The following instruments were used: the five-item version of the International Index of Erectile Function, personal demographics and medical variables. RESULTS The results showed that the prevalence of erectile dysfunction among the low anterior resection patients was 97·0% (129/133), and the erectile dysfunction prevalence was 75·9% (44/58) for the males who underwent colectomy. The generalised linear model showed that after controlling for hypertension and stoma, the low anterior resection group had worse sexual function than those in the colectomy group, and stoma was also a factor that impacted patients' sexual function. The results also revealed that only 32·8-35·3% of health care providers talked about sexual dysfunction with people who have rectal cancer prior to surgery. CONCLUSION This study demonstrated that men who have undergone low anterior resection have a high risk of sexual dysfunction and that health care professionals infrequently discuss these issues with patients. RELEVANCE TO CLINICAL PRACTICE When patients are diagnosed with rectal cancer and before they undergo surgery, an assessment and discussion of sexual function issues should be incorporated into standard care. Continued follow-up after hospital discharge and evaluations of sexual function are vital factors for male postoperative rectal cancer patients.

Abstract
A 52-year-old woman was diagnosed with rectal hemangioma that had resulted in chronic bleeding. Klippel-Trenaunay syndrome was diagnosed by clinical examination. She was referred 30 years later because of progressive anemia. Colonoscopy revealed multiple bluish, polypoid nodules with severe vascular congestion and varicosis that had circumferentially spread along the wall from the dentate line to the rectosigmoid lesion. Selective abdominal angiography indicated that the hemangioma fed from the sigmoid artery and superior rectal artery. Doppler transrectal ultrasonography showed heterogeneous lesions with hypoechoic areas mostly in the submucosal layer, partly forming the mosaic pattern of the color flow signal in the intersphincteric layer on the oral side from the dentate line to 1 cm. Anterior resection and coloanal anastomosis with covering ileostomy was performed. Using a transanal approach, mucosectomy and intersphincteric resection were performed based on the Doppler transrectal ultrasonography results. There were no intraoperative complications, and her anemia resolved postoperatively.

Abstract
AIM A poor functional outcome is often reported after total mesorectal excision (TME) for rectal cancer, especially when sphincter-saving resection with intersphincteric dissection is performed for low tumours. Anal sphincter rehabilitation is widely proposed for faecal incontinence. Very few studies have reported results to improve anal dysfunction following rectal surgery. This prospective study aimed to assess the benefits of sphincter training after TME in terms of functional outcome and quality of life. METHODS Anal sphincter training was performed in patients undergoing laparoscopic sphincter-saving TME for rectal cancer. Rehabilitation was performed after ileostomy closure. This group was compared with 24 matched patients. Assessment included one functional and two quality of life questionnaires (SF-36 Health Status and Faecal Incontinence Quality of Life score). RESULTS From 2007 to 2009, 22 patients underwent laparoscopic TME. The median follow-up after stoma closure was 21.2 (range 8-46) months. The mean stool frequency per day was significantly lower after sphincter training (2.6 in the training group vs 4.0 in the control group, P=0.025). Following rehabilitation, patients complained significantly less about dyschezia (22 vs 63%, P=0.008). Both groups had similar continence (Wexner score 8.3 after training vs 9.9 in controls, NS). Quality of life was significantly improved by sphincter training as measured by the vitality (P=0.004) and mental functioning (P=0.02) subscales on the SF-36 Health Status questionnaire and by the depression and self-perception (P = 0.005) categories of the Faecal Incontinence Quality of Life score. CONCLUSION This study suggests that anal sphincter training following TME could decrease stool frequency and improve both general and specific quality of life.

Abstract
In the treatment of distal rectal cancer, abdominoperineal resection is traditionally performed. However, the recognition of shorter safe distal resection line, intersphincteric resection technique has given a chance of sphincter-saving surgery for patients with distal rectal cancer during last two decades and still is being performed as an alternative choice of abdominoperineal resection. The first aim of this study is to assess the morbidity, mortality, oncological, and functional outcomes of intersphincteric resection. The second aim is to compare outcomes of patients who underwent intersphincteric resection with the outcomes of patients who underwent abdominoperineal resection.

Abstract
Purpose. The purpose of this study was to analyze the safety and feasibility of laparoscopic intersphincteric resection (ISR) combined with transanal rectal dissection (TARD) for T3 low rectal cancer in a narrow pelvis. Methods. We studied 20 patients with a narrow pelvis of median body mass index 25.3 (16.9–31.2). Median observation period was 23.6 months (range 12.2–56.7). Results. Partial, subtotal, and total ISR was performed in 15, 1, and 4 patients, respectively. Median duration of TARD was 83 min (range 43–135). There were no major complications perioperatively or postoperatively. Surgical margins were histologically free of tumor cells in all patients, and there was no local recurrence. Excluding urgency, frequency of bowel movements, and incontinence status improved gradually after stoma closure. Conclusion. Laparoscopic ISR combined with TARD is technically feasible for selective T3 low rectal cancer in patients with a narrow pelvis.

Abstract
INTRODUCTION Early rectal cancer (ERC) is adenocarcinoma that has invaded into, but not extended beyond, the submucosa. Endoscopic or minimal access surgical procedures, such as laparoscopic resection, have emerged as a useful tool in the surgical treatment of such diseases. The aim of this study is to present and analyze the feasibility, the short- and long-term results of laparoscopic colorectal surgery (LCS) in patients with ERC. PATIENTS AND METHODS Between 2002 and 4/2011, a total of 164 patients with colorectal cancer underwent laparoscopic surgery (LS). Of these, 7 patients (4.2%) had ERC and underwent laparoscopic anterior resection (LAR). The median follow-up was 41 months. RESULTS The mean operative time was 2.5 h. None of the laparoscopic procedures was converted to open surgery. Liquids and solid food were started on median postoperative days 1 and 3, respectively. The median length of postoperative stay was 5 days. Postoperative complications occurred in 2 patients (28.5%), including wound infection in one patient (14.2%) and atelectasis in one patient (14.2%). None of the patients required an urgent re-operation. There was no mortality related to LS. CONCLUSIONS LS for ERC can be used as a strategy sited between endoscopic mucosal resection and open anterior resection with beneficial long- and short-term results. It appears as a technically and oncologically safe procedure when performed by surgeons with sufficient experience in laparoscopic techniques.

Abstract
BACKGROUND In distal rectum cancers, when the sphincters are not affected and it is not possible to perform a coloanal anastomosis because of the presence of comorbidities or the advanced age of the patient, a low Hartmann resection with total mesorectal excision can be performed. Low Hartmann resection is usually considered to be a shorter procedure and to have an inferior morbidity compared with abdominoperineal resection of the rectum. OBJECTIVE This study aimed to compare the postoperative outcome of a series of patients with low rectal cancer who have undergone either low Hartmann resection or abdominoperineal resection. DESIGN This study is a retrospective analysis of data collected in a prospective database. SETTINGS This study was conducted in a specialized Colorectal Unit, Department of Surgery, of a tertiary teaching hospital. PATIENTS Patients who underwent low Hartmann or abdominoperineal resection for rectal cancer between 1996 and 2009 at our specialized Colorectal Unit were considered. INTERVENTIONS The main interventions were low Hartmann resection vs abdominoperineal resection. MAIN OUTCOME MEASURES The main outcome measures were 60-day morbidity and mortality. RESULTS The pelvic abscess rate was 12.2% in patients who underwent low Hartmann resection and 3.0% in those who underwent abdominoperineal resection (P = .02). The reoperation rate was 14.6% in the Hartmann group and 3.8% in the abdominoperineal group (P = .013). The rehospitalization rates in the Hartmann and abdominoperineal groups were 7.3% and 0.7% (P = .015). No differences were found in the other variables analyzed. At multivariate analysis, the surgical technique performed was the only independent risk factor for pelvic abscess development, readmission, and reoperation. LIMITATIONS : This study was limited by its retrospective nature. CONCLUSION In our series, low Hartmann resection was associated with higher pelvic abscess, reoperation, and readmission rates. These findings suggest that in patients with rectal cancer without sphincter infiltration and who are unsuitable for coloanal anastomosis, abdominoperineal resection should be a valid alternative to low Hartmann resection.

Abstract
PURPOSE The purpose of this study was to evaluate the outcome and genitourinary complications of super-low anterior resection (SLAR) followed by adjuvant radiochemotherapy in the management of patients with low rectal cancer. METHOD One hundred and six low rectal cancer patients managed with SLAR were analyzed retrospectively. RESULTS There were seven patients who failed to follow up, and the 5-year survival rate was 65.7% (65/99). There were 35 patients (35.4%) who developed distant metastases, and 12 (12.1%) had local recurrence. The local recurrence rates were 21.1% (4/19), 7.1% (2/28), 5.9% (1/17), and 0% (0/2) in the patients with tumor distance of less than or equal to 2 cm, ranging from 2.1 to 3.0, from 3.1 to 4.0, from 4.1 to 5.0, and more than 5 cm, respectively. This implied local recurrence rate increased against the distance between the lower margin of tumor and resection line. Ninety-eight of 106 rectal patients had complete data of questionnaire: 58 scored 1, 32 scored 2, 7 scored 3, and 1 score 4. This revealed that the fecal function of most patients (91.8%, 90/98) was normal or nearly normal. Twenty-four of 37 males suffered from sexual dysfunction, and among them, eight were impotent (all older than 70 years), and 29 had retrograde ejaculation. Meanwhile, seven of 35 females suffered from sexual problem, 1 had dyspareunia, seven had decreased lubrication, and one had inability to achieve orgasm. CONCLUSIONS SLAR followed by adjuvant radiochemotherapy can effectively control local-regional disease and can be one choice of avoiding the functional morbidity of abdominoperineal resection.

Abstract
Klippel-Trénaunay syndrome is a rare congenital vascular disorder characterized by varicose veins, hypertrophy of the soft tissues and bones, and hemangiomas. Although colorectal angiomatosis is uncommon, this association can lead to life-threatening complications because of acute or chronic bleeding. We report a patient with Klippel-Trénaunay syndrome who presented with transfusion-dependent anemia secondary to chronic rectal bleeding. Endoscopy and image studies revealed venous angiomata involving the rectum and distal sigmoid colon. We performed a laparoscopic ultralow anterior resection with intersphincteric dissection, obtaining good results. After a follow-up of 20 months the patient did not present hematochezia and maintained fecal continence.

Abstract
Surgery for the treatment of colorectal diseases has been evolving rapidly recently. In addition to classical surgical procedures (colectomy, abdominoperineal resection), new surgical procedures include coloproctectomy with creation of an ileoanal anastomosis and ileal pouch, pelvic reconstructions (omentoplasty, placement of myocutaneous flaps) and creation of different colic anastomoses after anterior rectal resection. Even if computed tomography and fluoroscopic contrast examinations are still commonly used to assess postoperative changes and complications, especially infections, pelvic magnetic resonance imaging is useful to depict postoperative changes, detect complications such as fistulas and tumor recurrence in patients who have undergone surgery for primary or recurrent rectal disease. The main surgical techniques, their respective indications and postsurgical imaging features will be discussed. The main complications and imaging work-up will also be reviewed.

Abstract
PURPOSE This study was designed to assess the impact of social deprivation on rates of abdominoperineal excision of the rectum in the United Kingdom. METHODS Data were extracted from the Association of Coloproctology of Great Britain and Ireland Colorectal Cancer Database (2000-2005). Social deprivation was assessed by using the Index of Multiple Deprivation (2004) score. Logistic regression was performed to identify independent predictors of nonrestorative surgery. RESULTS A total of 12,128 patients underwent anterior resection or abdominoperineal excision for Dukes A-C cancer in 101 centers; 2,625 patients (21.6 percent) underwent abdominoperineal excision (median, 20.8 (interquartile range, 16.5-27.9) percent per unit). Abdominoperineal excision rates decreased from 24.3 to 18.2 percent (P < 0.001) and varied between the least and most deprived groups from 18 to 26.4 percent, respectively (P < 0.001). Independent predictors of abdominoperineal excision were: year of surgery (odds ratio = 0.855 per year increase, P < 0.001), female vs. male gender (odds ratio = 0.82, P < 0.001), use of neoadjuvant radiotherapy (odds ratio = 2.4, P < 0.001), and social deprivation (most vs. least deprived: odds ratio = 1.638, P < 0.001). CONCLUSIONS Abdominoperineal excision rates vary considerably between centers. Gender and deprivation status independently predict formation of a permanent stoma. These results have important implications for intercenter comparisons of surgical quality and may suggest inequalities in health care provision.

Abstract
Abstract
Background
The purpose of this study was to determine the long-term outcomes of patients undergoing endocavitary contact radiation therapy (ECR) for stage I rectal cancer.
Methods
A database of patients treated with ECR for biopsy-proven rectal adenocarcinoma from July 1986 to June 2006 was reviewed retrospectively. Only patients with primary, non-metastatic, ultrasonographically staged T1 N0 and T2 N0 cancer who had no adjuvant treatment were included. Patients received a median of 90 (range 60–190) Gy contact radiation, delivered transanally by a 50-kV X-ray tube in two to five fractions.
Results
Of 149 patients, 77 (40 T1, 37 T2) met the inclusion criteria. Median age was 74 (range 38–104) years, and median follow-up 69 (range 10–219) months. ECR failed in 21 patients (27 per cent) (persistent disease, four; recurrence, 17), of whom ten remained disease free after salvage therapy. The estimated 5-year disease-free survival rate was 74 (95 per cent confidence interval 63 to 83) per cent after ECR alone, and 87 (76 to 93) per cent when survival after salvage therapy for recurrence was included.
Conclusion
ECR is a minimally invasive treatment option for early-stage rectal cancer. However, similar to other local therapies, ECR has a worse oncological outcome than radical surgery.

Oncologic outcomes after radical surgery following preoperative chemoradiotherapy for locally advanced lower rectal cancer: abdominoperineal resection versus sphincter-preserving procedure. Ann Surg Oncol 2009; 16:1266-73.

Abstract
BACKGROUND Over the past several years, preoperative chemoradiotherapy (CRT) has contributed remarkably to make more sphincter-preserving procedure (SPP) possible for lower rectal cancer. The aim of this study was to compare the outcomes between abdominoperineal resection (APR) and SPP after preoperative CRT in patients with locally advanced lower rectal cancer. METHODS A retrospective investigation was conducted with a total of 122 patients who underwent radical surgery combined with preoperative CRT for locally advanced lower rectal cancer. Of these, 50 patients underwent APR and 72 received SPP. Surgery was performed 6-8 weeks after completion of preoperative CRT. Oncologic outcomes were compared between the two groups, and the clinicopathologic factors affecting the treatment outcomes were evaluated. RESULTS Circumferential resection margin (CRM) involvement (P = 0.037) and postoperative complication rate (P = 0.032) were significantly different between APR and SPP. Patients who underwent APR had a higher 5-year local recurrence (22.0% vs. 11.5%, P = 0.028) and lower 5-year cancer-specific survival (52.9% vs. 71.1%, P = 0.03) rate than those who underwent SPP. Pathologic N stage was the most critical predictor for local recurrence and survival. CONCLUSIONS Our study shows that APR following preoperative CRT exhibited more adverse oncologic outcomes compared with SPP. This result may be due to higher rates of CRM involvement in APR even with preoperative CRT. We suggest that sharp perineal dissection and wider cylindrical excision at the level of the anorectal junction are required to avoid CRM involvement and improve oncologic outcomes in patients who undergo APR following preoperative CRT.

Abstract
Local excision is an alternative approach to radical proctectomy for rectal cancer, but from an oncologic standpoint, it is a compromise, and its role remains controversial. Careful patient selection is essential because local excision is generally considered only for early rectal cancer with no evidence of nodal metastasis, parameters that can be predicted by clinical examination, and various radiologic modalities with variable accuracy. In this review, we present the literature evaluating the oncologic adequacy of local excision, including transanal endoscopic microsurgery and the results of salvage surgery after local excision. An overview of local excision in the context of perioperative adjuvant therapies is included. Finally, we suggest a treatment algorithm for local excision in rectal cancer.

Abstract
BACKGROUND Early rectal cancer (ERC) is adenocarcinoma that has invaded into, but not extended beyond, the submucosa of the rectum (that is a T1 tumour). Local excision is curative for low-risk ERCs but for high-risk cancers such management is controversial. METHODS This review is based on published literature obtained by searching the PubMed and Cochrane databases, and the bibliographies of extracted articles. RESULTS AND CONCLUSION ERC presents as a focus of malignancy within an adenoma, as a polyp, or as a small ulcerating adenocarcinoma. Preoperative staging relies on endorectal ultrasonography and magnetic resonance imaging. Pathological staging uses the Haggitt and Kikuchi classifications for adenocarcinoma in pedunculated and sessile polyps respectively. Lymph node metastases increase with the Kikuchi level, with a 1-3 per cent risk for submucosal layer (Sm) 1, 8 per cent for Sm2 and 23 per cent for Sm3 lesions. Low-risk ERCs may be treated endoscopically or by a transanal procedure. Transanal excision or transanal endoscopic microsurgery may be inadequate for high-risk ERCs and adjuvant chemoradiotherapy may be appropriate. There is a low rate of recurrence after local surgery for low-risk ERCs but this increases to up to 29 per cent for high-risk cancers.

Abstract
OBJECTIVE To assess rates of abdominoperineal excision of the rectum (APER) for rectal cancer between centers and over time, and to evaluate the influence of patient characteristics, including social deprivation, on APER rate. METHODS Data on patients undergoing APER or anterior resection (AR) in England were extracted from a national administrative database for the years 1996 to 2004. The primary outcome was the proportion of patients presenting with rectal cancer undergoing APER. Hierarchical logistic regression was used to identify independent factors associated with a nonrestorative resection. RESULTS Data on 52,643 patients were analyzed, 13,109(24.9%) of whom underwent APER. The APER rate significantly reduced over the study period from 29.4% to 21.2% (P < 0.001). Operative mortality following AR decreased significantly during the period of study (5.1% to 4.2%, P = 0.002), while that following APER did not (P = 0.075). Male patients were more likely to undergo APER (P < 0.001), whereas those with an emergency presentation more commonly underwent AR (P < 0.001). Independent predictors of increased APER rate were male gender (odds ratio [OR] = 1.239, P < 0.001) and social deprivation (most vs. least deprived; OR = 1.589, P < 0.001), whereas increasing patient age (OR = 0.977, P = 0.027 per 10-year increase), year of study (2003/4 vs. 1996/7; OR = 0.646, P < 0.001) and initial presentation as an emergency (OR = 0.713, P < 0.001) were associated with lower APER rates. After accounting for case-mix, there was significant between-center variability in APER rates. CONCLUSION Socially deprived patients were more likely to undergo abdominoperineal resection. Significant improvements in rates of nonrestorative resection were seen over time but although short-term outcomes following AR have improved, those following APER have not. Permanent stoma rates following rectal cancer surgery may be considered a surrogate marker of surgical quality.

Abstract
PURPOSE This study was designed to assess the impact of pelvic radiotherapy on the incidence of complications and colostomy-free survival of patients after a coloanal anastomosis for rectal cancer. METHODS A total of 192 patients underwent a coloanal anastomosis between 1982 and 2001: 87 patients did not receive pelvic radiotherapy; 105 patients received pelvic radiotherapy (39 preoperative and 66 postoperative). Early and late complications requiring surgical intervention and the colostomy-free survival rate were assessed by retrospective review of patient records. RESULTS After a median follow-up of 62 months, 151 patients were alive. The most frequent complication was development of an anastomotic stricture (5-year rate of a stricture, 16 percent; 95 percent confidence interval, 10-21). Patients receiving pelvic radiotherapy had a higher rate of complications other than anastomotic strictures, including fecal incontinence, fistulas, abscesses, and bowel obstructions compared with patients not receiving pelvic radiotherapy (5-year rate: 20 percent (95 percent confidence interval, 10-29) vs. 5 percent (95 percent confidence interval, 0-10); P = 0.001). Patients receiving pelvic radiotherapy had a lower colostomy-free survival than did patients not receiving pelvic radiotherapy (5-year colostomy-free rate: 72 percent (95 percent confidence interval, 62-84) vs. 92 percent (95 percent confidence interval, 86-98); P < 0.001). There was no significant difference in the colostomy-free survival of patients receiving preoperative and postoperative pelvic radiotherapy. CONCLUSIONS After coloanal anastomosis, a significant number of patients will have complications requiring surgical intervention, and some will require a permanent colostomy. Pelvic radiotherapy, whether it is administered preoperatively or postoperatively, significantly increases the need for a permanent colostomy.

Abstract
The anal sphincter preservation rate (ASPR) according to tumor level and neoadjuvant chemoradiotherpy (CRT) has not been fully evaluated. Therefore, the aim of this study was to evaluate the correlation between the tumor level, neoadjuvant CRT, and the ASPR in rectal cancer patients. We studied 544 patients (tumor level, 0-6 cm) who underwent curative resection for rectal cancer between 1991 and 2005. Patients were divided six into groups according to tumor level over 1-cm intervals, and the ASPR was evaluated in patients with and without neoadjuvant CRT according to tumor level. Sphincter preservation surgery was performed in 191 patients, and 86 patents underwent neoadjuvant CRT. The overall ASPR was 43.0% (37/86) in patients with neoadjuvant CRT and 33.6% (154/458) in patients without neoadjuvant CRT (P=0.094). In an analysis according to tumor level, the ASPR was 0.0 vs 0.0% in <or=1 cm, 0.0 vs 2.1% in 1<or=2 cm (P=0.589), 11.8 vs 16.8% in 2<or=3 cm (P=0.599), 55.6 vs 20.2% in 3<or=4 cm (P=0.001), 57.7 vs 45.9% in 4<or=5 cm (P=0.227), and 66.7 vs 69.5% in 5<or=6 cm (P=0.827). Neoadjuvant CRT did not increase the ASPR in tumor level within <or=6 cm. However, for the tumor level (3<or=4 cm), neoadjuvant CRT significantly increased the ASPR.

Abstract
The main problem associated with rectal cancer treatment is tumor recurrence. Randomized controlled studies have shown that adjuvant preoperative radiation therapy is effective for reducing local recurrence. These studies have also demonstrated that there are groups of rectal cancer patients with differing degrees of risk for local recurrence. At one end of the spectrum is the low-risk group: patients with superficial rectal cancer, who can be treated with surgery alone. At the other end is the high-risk group: patients with a close or involved resection margin at total mesorectal excision, the very advanced tumors that require a longer course of chemotherapy and radiation therapy, and extensive surgery. Paramount for this selection and differentiated treatment is a reliable preoperative test that can be used to distinguish these groups of patients. In this review article, we will discuss the role of high-resolution phased array MRI among the other imaging modalities such as endorectal MRI, endorectal US, and CT. We will also discuss and illustrate MR imaging results in terms of T stage, circumferential resection margin, locally advanced rectal cancer, and N stage.

Abstract
Organ preservation with maintenance of function in the treatment of rectal cancer is highly valued by patients. Although most patients with resectable rectal cancer can undergo a sphincter-sparing radical procedure, there are patient, tumor, surgeon, and treatment factors that influence the ability to restore intestinal continuity after radical resection. Although population-based data suggest that the rate of sphincter preservation is lower than could be obtained at expert centers, there are patients in whom low anterior resection with colo-anal anastomosis is not technically feasible and/or oncologically sound. Additionally, resection with ultralow anastomosis results in functional compromise in many patients. Local treatment of rectal cancer aims to decrease the morbidity and the functional sequelae associated with radical resection; however, local excision is associated with a higher rate of local recurrence than is radical resection. Strict selection criteria are essential when considering local excision, and patients should be informed of the risk of local recurrence. The use of adjuvant therapy with local excision, particularly in patients with T2 lesions, has promise but should be considered only as part of a clinical trial.

Abstract
Pelvic magnetic resonance (MR) imaging is useful for identification of postoperative changes, complications, and disease recurrence in patients who have undergone surgery for primary or recurrent anorectal disease. Commonly used interventions include treatment for anorectal carcinoma: anterior rectal resection with or without creation of different colic anastomoses and abdominoperineal excision with or without pelvic reconstruction (omentoplasty, placement of myocutaneous flaps). Other common interventions include treatment for inflammatory bowel disease (coloproctectomy with or without creation of an ileoanal anastomosis and ileal pouch) and treatment for fistulas (placement of flaps or setons). Postoperative anatomic changes and formation of scar tissue can usually be identified with consecutive MR imaging examinations. Pelvic MR imaging is an accurate technique for assessment of complications including anastomotic leakage, septic complications such as fistulas and abscesses, neoplastic recurrence, and other less common complications (perineal hernia, peritoneal pseudocyst). The sophisticated surgical procedures used in rectal surgery can alter normal anatomy and make image interpretation difficult. Thus, familiarity with the appearances of postoperative anatomic changes, complications, and tumor recurrence is essential for accurate MR imaging evaluation after surgery for anorectal disease.

Abstract
OBJECTIVE Many patients experience disordered defaecation after low anterior resection of the rectum (LARR). We analysed the anorectal function of these patients to determine which factors might contribute to this problem. PATIENTS AND METHODS Between November 2002 and January 2004, 18 consecutive patients (11 males and 7 females) who underwent LARR with total mesorectal excision (TME) for rectal cancer were assessed by anorectal manometry, balloon proctometry and the Wexner continence questionnaire before operation and at 6 months and 1 year following stoma closure. Sixteen volunteers (11 males and 5 females) were evaluated for comparison. Stepwise logistic regression was performed for variables that were highly significant at univariate analysis. RESULTS The mean daily preoperative stool frequency was 2, mean basal pressure (MBP) 43.12 cm H(2)O, maximum threshold volume (MTV) 181.8 ml, length of high-pressure zone (HPZ) 3.11 cm and the rectoanal inhibitory reflex (RAIR) was present in all the patients. Twelve months after stoma closure, the stool frequency was 3.3, MBP 37.7 cm H(2)O, MTV 146.3 ml, length of HPZ 2.88 cm and Wexner score 4.37. Comparing patients having a good anorectal function (Wexner score > or = 5) with those having an unsatisfactory function, we found that, on multivariate analysis, the factors that independently contributed to a poor outcome at 12 months after operation were the absence of RAIR as well as an MTV and HPZ below the fifth percentile of normal individuals. CONCLUSIONS Many patients undergoing LARR with TME for rectal cancer experience an anterior resection syndrome that persists for at least 1 year. Those with no RAIR and subnormal MTV and HPZ lengths can be predicted to have an unsatisfactory outcome.

Abstract
PURPOSE Quality of life is an important outcome measure that has to be considered when deciding treatment strategy for rectal cancer. The aim of this study was to find out the impact of surgery-related adverse effects on quality of life. METHODS The RAND-36 questionnaire and questionnaires assessing urinary, sexual, and bowel dysfunction were administered to 94 patients with no sign of recurrence a minimum of one year after curative surgery. Results were compared with age-matched and gender-matched general population. RESULTS Eighty-two (87 percent) patients answered the questionnaires. Major bowel dysfunction was as common after high anterior resection as after low anterior resection. Urinary complaints occurred as often after anterior resection as after abdominoperineal resection, but sexual dysfunction was more common after abdominoperineal resection. Overall, the patients reported better general health perception but poorer social functioning than population controls. In particular, elderly patients reported a significantly better quality of life in many dimensions than their population controls. There was no significant difference in quality of life between treatment groups. Major bowel dysfunction after anterior resection impaired social functioning compared with that of patients without such symptoms. Urinary dysfunction impaired social functioning and impotence impaired physical and social functioning. CONCLUSIONS Quality of life after rectal cancer surgery is not worse than that of the general population. The major adverse impact of bowel and urogenital dysfunction is on social functioning. These adverse effects need to be discussed with the patient and preoperative function needs to be taken into account when choosing between treatment options. Permanent colostomy is not always the factor that disrupts a person's quality of life most.

Abstract
AIMS To evaluate whether pre-operative chemo-radiotherapy (CRT) improves the sphincter preservation rate for distal rectal cancers within 3 cm of the anal verge. METHODS Between January 2001 and December 2004, 49 patients underwent surgery with or without pre-operative CRT for primary rectal adenocarcinoma within 3 cm of the anal verge. Clinical data were retrospectively reviewed, including stage workups, surgical records and pathology records to determine sphincter preservation rate and the factors influencing sphincter preservation. RESULTS Of 49 patients with rectal tumours within 3 cm of the anal verge, 31 underwent pre-operative CRT followed by surgery (CRT group), and 18 underwent surgery alone (non-CRT group). Sphincter preservation was possible in 11 of 31 CRT patients, and only one of 18 non-CRT patients (p=0.036). The factors most influencing sphincter preservation were reduction in tumour size (p=0.005) and downstaging (p=0.001) following pre-operative CRT. CONCLUSION We could observe that sphincter preservation was improved in CRT group with statistical significance when compared to non-CRT group in our study patients with rectal cancer within 3 cm of the anal verge.

Abstract
PURPOSE Sphincter-preserving surgery is technically feasible for many rectal cancers, but functional results are not well understood. Therefore, the purpose of this study was to develop an instrument to evaluate bowel function after sphincter-preserving surgery. METHODS A 41-item bowel function survey was developed from a literature review, expert opinions, and 59 patient interviews. An additional 184 patients who underwent sphincter-preserving surgery between 1997 and 2001 were asked to complete the survey and quality-of-life instruments (Fecal Incontinence Quality of Life, European Organization for Research and Treatment of Cancer QLQ 30/Colorectal Cancer 38). A factor analysis of variance was performed. Test-retest reliability was evaluated, with 20 patients completing two surveys within a mean of 11 days. Validity testing was done with clinical variables (gender, age, radiation, length of time from surgery), surgical variables (procedure: local excision, low anterior resection, coloanal anastomosis), reconstruction (J-pouch, straight), anastomosis (handsewn, stapled), and quality-of-life instruments. RESULTS The survey response rate was 70.1 percent (129/184). Among the 127 patients with usable data, 67 percent were male, the median age was 64 (range, 38-87) years, and the mean time for restoration of bowel continuity after sphincter-preserving surgery was 22.9 months. Patients had a median of 3.5 stools/day (range, 0-30), and 37 percent were dissatisfied with their bowel function. Patients experienced a median of 22 symptoms (range, 7-32), with 27 percent reported as severe, 37 percent as moderate, and 36 percent as mild. The five most common symptoms were incomplete evacuation (96.8 percent), clustering (94.4 percent), food affecting frequency (93.2 percent), unformed stool (92.8 percent), and gas incontinence (91.8 percent). The factor analysis identified 14 items that collapsed into three subscales: FREQUENCY (alpha = 0.75), DIETARY (alpha = 0.78), and SOILAGE (alpha = 0.79), with acceptable test-retest reliability for the three subscales and total score (0.62-0.87). The instrument detected differences between patients with preoperative radiation (n = 67) vs. postoperative radiation (n = 15) vs. no radiation (n = 45) (P = 0.02); local excision (n = 10) vs. low anterior resection (n = 55) vs. coloanal anastomosis (n = 62) (P = 0.002); and handsewn (n = 18) vs. stapled anastomosis (n = 99) (P = 0.006). The total score correlated with 4 of 4 Fecal Incontinence Quality of Life (P < 0.01) and 9 of 17 European Organization for Research and Treatment of Cancer subscales (all P < 0.01). CONCLUSIONS Patients undergoing sphincter-preserving surgery for rectal cancer have impaired bowel function, and those treated with radiation, coloanal anastomoses, or handsewn anastomoses have significantly worse function. This reliable and valid instrument should be used to prospectively evaluate bowel function after sphincter-preserving surgery in patients undergoing rectal cancer therapy.

Abstract
OBJECTIVE To assess oncologic outcome of patients treated by conservative radical surgery for tumors below 5 cm from the anal verge. SUMMARY BACKGROUND DATA Standard surgical treatment of low rectal cancer below 5 cm from the anal verge is abdominoperineal resection. METHODS From 1990 to 2003, patients with a nonfixed rectal carcinoma at 4.5 cm or less from the anal verge and without external sphincter infiltration underwent conservative surgery. Surgery included total mesorectal excision with intersphincteric resection, that is, removal of the internal sphincter, to achieve adequate distal margin. Patients with T3 disease or internal sphincter infiltration received preoperative radiotherapy. RESULTS Ninety-two patients with a tumor at 3 (range 1.5-4.5) cm from the anal verge underwent conservative surgery. There was no mortality and morbidity was 27%. The rate of complete microscopic resection (R0) was 89%, with 98% negative distal margin and 89% negative circumferential margin. In 58 patients with a follow-up of more than 24 months, the rate of local recurrence was 2% and the 5-year overall and disease-free survival were 81% and 70%, respectively. CONCLUSIONS The technique of intersphincteric resection permits us to achieve conservative surgery in patients with a tumor close to or in the anal canal without compromising local control and survival. Tumor distance from the anal verge is no longer a limit for sphincter-saving resection.
